Question

我收到此消息“mscorlib.dll中出现'System.InvalidOperationException'类型的第一次机会异常”

但我不知道为什么会这样，这是我的代码：

    //declarations
    private List<Proces> tempProcess;
    private List<Proces> NotScheduled;
    private List<Proces> kolejka;
    private List<Proces> pokolenie;
    private List<float> licznikLB;


//function i have problem with
    protected override void bnbalg()
    {

        foreach (var proces in NotScheduled)
        {
            tempProcess= NotScheduled;
            tempProcess.RemoveAt(0);
            float LB = CalculateLB(tempProcess);
            if (proces.TerminZakonczenia < LB)
            {
                pokolenie.Add(proces);
                licznikLB.Add(LB);
            }
        }
        kolejka.Add(pokolenie[licznikLB.IndexOf(licznikLB.Min())]);
        NotScheduled.Remove(pokolenie[licznikLB.IndexOf(licznikLB.Min())]);
        tempProcess.Clear();
        pokolenie.Clear();
        licznikLB.Clear();
        if (NotScheduled.Any())
        {
            bnbalg();
        }

    }

似乎在“foreach”的第一个循环中正确计算每一个，但在下一个循环中，当tempProcess减1时我得到了异常消息，请帮我解决这个问题。

编辑：添加了异常详细信息和固定名称切换但仍然发生
